Take your top 32* artists and pit them against each other in a knock-out style tournament. For each "match", randomly shuffle the artist's tracks and play the first track, that comes up. After you play both artist's tracks, the artist with the track you preferred goes forward, and so on and so forth.

Some other rules about tracks:

1. No track can be played twice2. No live versions of a track to be played if there are album versions

Here's how my tournament went (artist play rank in brackets):

* I skipped my 29th artist Anneke van Giersbergen & Danny Cavanagh because the only thing they made together was one live album on which they play songs from their own albums and some covers. Instead I added my number 33, which is Nightwish.

I just realized that I've been using last.fm for nearly 6 years without ever truly engaging. I've scrobbled over 200k songs and only have a handful of loves, friends, groups or lasting impression that I've ever been here. I suppose it's time to change that and touch upon who I am as a music listener for anyone who cares to know.
